Prosecutors: Toddler said "school" minutes before dad left him in hot car

The trial of the Cobb County father accused of leaving his 22-month-old to die in a hot car is underway, more than two years after the incident took place.

Ross Harris is facing numerous charges, including malice murder, felony murder and cruelty to children, in the death of his young son, Cooper. The boy was found in the back seat of Harris’ SUV back in June 2014.

Harris claimed that it was a tragic accident.

During opening statements, the prosecutors brought to light new details of the day Cooper died as well as what Harris has been doing leading up to the day including:

The prosecution said Harris mentioned Cooper said "school" after breakfast, knowing he was headed to daycare.

During detainment, Harris complained to officers that it was hot in the back of their patrol car.

Harris backed car into a space with no camera when at work. Prosecutor insists he saw his son.

Two days prior to son's death, Harris met with a prostitute in a Marietta hotel and messaged with a 15-year-old girl.

While being interviewed, Harris told detectives that he "forgot to do a second look," the prosecution said.

Harris complained about jail having an uncomfortable bed and tin toilet.

Harris told numerous women online, in person that he was unhappy in marriage. He lies to police about phone code to detectives. Tried to talk his way out of the crime. Familiarized himself with what would be his defense and tried to argue against them. Tries to get them to not do a “second look again.” Refers to TV: “There’s a man just like me who’s now an advocate.” Brings up his dispatcher job in Tuscaloosa. Says he saw a video on internet (“How Hot Does It Get In A Parked Car?”) about animals left in car.
